A flow chart for the classification of igneous rocks in HTML']HTML - Is a Web browser another way for teaching earth sciences?

The hypertext mark-up language (HTML) is a mark-up system used co create hypertext documents in use by the world-wide web (WWW). A flow chart for the classification of igneous rocks was written in HTML 3.2, a specification conforming to International Standard ISO 8879. HTML is ideal in teaching earth sciences on the Internet due to step by step nature of the classification of rocks because it is relatively straightforward to develop a series of graphically rich Web pages. The flow chart makes wide use of link techniques for references and terminology. As an essential result of the step by step technique, as proposed by the Recommendations of the International Union of Geological Sciences Subcommission on the Systematics of Igneous Rocks, the user should be able to classify any rock specimen with an appropriate nomenclature.
